The U-shaped hull provides a spacious interior and stable structure for comfortable use on the water. The Inflatable Boat with Air Keel also features a three-chamber system, with independent air chambers contributing to flotation and overall stability. The high-density PVC tubes are designed for regular water use and provide durable strength and resistance. As a Boat Manufacturer, SIRI SPORTS uses the supplied 0.9T PVC construction across the SIM series. This makes the Boat suitable for buyers looking for a practical inflatable structure with an air keel.
